About the Kongsberg 334895

The Kongsberg 334895 is the RAi-10tcxe, the thermocouple input module of Kongsberg's K-Chief 600 automation system. It measures temperature on 10 channels from thermocouples of types J, K, T, E, R, S, B or N, with cold-junction compensation built in and ranges up to 1200 °C for type K. It checks limits, time-stamps alarms and events and reports over a redundant CANopen field bus.

What is the 334895 used for?

Kongsberg describes the RAi-10tcxe as particularly suited to engine exhaust temperatures. It is placed close to the engine, in a suitable cabinet or on the engine itself, which keeps the sensitive thermocouple wiring short.

Lifecycle and successor

Active.

Before you order

What to photograph or confirm so the right unit is quoted.

Check the part number 334895 and the RAi-10tcxe marking on the module label, with its revision. The earlier RAi-10TC (8100161) is a different part from the older DataChief C20 / K-Chief 500 generation. Send a label photo and the vessel name or IMO number.
